Unit 3Section 1Listening课件 - 2025-2026学年沪教版（2024）八年级英语上册

该初中英语课件围绕“数字技术如何改变生活”核心问题，聚焦笔记本电脑的尺寸、重量、内存等基本信息及购买考虑因素，通过“猜测购物方式（线下到线上）”导入，结合讨论任务搭建知识支架，为听力理解（对话获取信息）奠定基础。 其亮点在于任务链设计（讨论-听力提取-信息整合-生活分享），通过真实购物对话情境培养语言能力（听力提取、口语表达）和思维品质（分析比较笔记本参数），如Task 2-3听对话回答问题、完成表格。采用任务型教学，语言点拓展（如laptop构词法）助力词汇掌握，学生能提升听力技能与实际运用能力，教师可借助结构化任务高效开展教学。
